First, the characters in an NSString are Unicode, not ASCII. If you
need ASCII, you will have to convert them by creating a C string with
one of NSString's methods lossyCString, dataUsingEncoding:
NSASCIIStringEncoding, or dataUsingEncoding: NSASCIIStringEncoding
allowLossyConversion: YES. Read the documentation on NSData to see how
to access the length and bytes of an NSData object.
If the Unicode characters are good enough for you, you can obtain them
through characterAtIndex:. You can then format them as hexadecimal with
[NSString stringUsingFormat: @"x", character].
